320w ago - Has the Wii's bubble finally burst? Sales figures from Japanese retailers show the Wii is the only console to show negative growth over the last week.

While it is far too soon to start shouting the demise of the Wii from the rooftops, Nintendo saw unit sales of its home console fall by 3,000 units, allowing the PlayStation 3 to close the sales gap between the two consoles from 12,000 units two weeks ago, to just under 6,000 units this week.

The Wii is showing the least resilience of all systems in the current slump in the Japanese hardware market, seeing sales slump 96,000 since the beginning of the year.

It's not all doom and gloom in the Nintendo camp however, as sales of the DSi rose by 4,000 units, perhaps suggesting that the market for the Wii is starting to become saturated.
